level)
The oil will drain more rapidly and completely when the engine is warm.
1.
Remove the dipstick.
2.
Place a suitable oil container under the drain hole.
3.
Remove the drain plug and allow all of the oil to drain out.

5.
Reinstall the dipstick.
Oil Capacity = 37 oz (1.1 L)
2) Maintenance of air filter
A dirty air filter can restrict air flowing into the carburetor. To keep the carburetor
in good working condition, please service the air filter periodically (clean air filter
element after 20h of use). If the engine is being operated in an extremely dusty
area, clean the filter more often.
1.
Loosen the Fasteners from the Air filter Cover and remove the Cover.
Note:
The Cover fasteners are captive and are supposed to stay assembled to the
Cover when the Cover is removed.
2.
Remove the Foam Element and Air Filter from the engine
3.
Lightly tap or shake the dust from the Air Filter. Clean the Foam Element with
soapy water.
Note:
If the foam Pre-cleaner (#37336) or paper filter (#37337) is too dirty to clean
(clogged) or damaged you must replace them with new ones.
4.
Clean the Air Filter Cover and inner surface with wet cloth, be careful not to
allow the dust to enter into the Air Cleaner Case Body.
5.
Reinstall the Air Filter and Foam Element.
6.
Reinstall the Air Filter Cover and secure with the Fasteners.
